Wait a f ew minutes af ter turning the
engine of f bef ore you check the oil.Remove the dipstick (orange loop).
Wipe of f the dipstick with a clean
cloth or paper towel.
Insert the dipstick all the way back
into its hole. Remove the dipstick again, and
check the level. It should be
between the upper and lower
marks.
If it is near or below the lower mark,
see on page .Look at the coolant level in the
radiator reserve tank. Make sure it is
between the MAX and MIN lines. If
it is below the MIN line, see
on page f or
inf ormation on adding the proper
coolant.

The f ollowing f actors can lower your
vehicle’s f uel economy:
Aggressive driving (hard
acceleration and braking)
Excessive idling, accelerating and
braking in stop-and-go traf f ic
Cold engine operation (engines
aremoreefficientwhenwarmed
up)
Driving with a heavy load or the
air conditioner running
Improperly inf lated tires
A properly maintained vehicle
maximizes f uel economy. Poor
maintenance can signif icantly reduce
f uel economy. Always maintain your
vehicle according to the maintenance
messages displayed on the
inf ormation display (see on page ).
For example: Rapid
acceleration, abrupt cornering,
and hard braking increase fuel
consumption.
If your vehicle has a
manual transmission, you can
boost your f uel economy by up
shif ting as early as possible.
Aerodynamic drag has a big ef f ect
on f uel mileage at speeds above 45
mph (75 km/h). Reduce your
speed and you reduce the drag.
Trailers, car top carriers, roof
racks and bike racks are also big
contributors to increased drag.
Idling
results in 0 miles per gallon.
An underinf lated tire increases
‘‘rolling resistance,’’ which reduces
f uel economy.
It puts a heavier
load on the engine, increasing f uel
consumption.
In
particular, a build-up of snow or
mud on your vehicle’s underside
adds weight and rolling resistance.
Frequent cleaning helps your f uel
economy.

Fill the f uel tank until the nozzle automatically clicks of f .
Reset trip counter to zero.
Record the total gallons (liters) needed to ref ill.
Follow one of the simple calculations above.
The A/C
puts an extra load on the engine
which makes it use more f uel. Use
the f resh-air ventilation when
possible.
Combine several short trips into
one. A warmed-up engine is more
f uel ef f icient than a cold one.
Direct calculation is the
recommended source of inf ormation
about your actual f uel economy.
Using f requency of f ill-ups or taking
f uel gauge readings are NOT
accurate measures of f uel economy.
Fuel economy may improve over the

10 seconds bef ore trying again.If the engine does not start within
15 seconds, or starts but stalls
right away, repeat step 4 with the
accelerator pedal pressed halfway
down. If the engine starts, release
pressure on the accelerator pedal
so the engine does not race.
If the engine fails to start, press
the accelerator pedal all the way
down, and hold it there while
starting to clear flooding. If the
engine still does not start, return

T he immobilizer system protects your
vehicle f rom thef t. If an improperly
coded key (or other device) is used, the
engine’s f uel system is disabled. For
more inf ormation, see page .
The engine is harder to start in cold
weather. Also, the thinner air f ound at
altitudes above 8,000 f eet (2,400
meters) adds to this problem.

whenever D3 is selected.
TheD3switchcanbeoperatedonly
when the ignition switch is in the ON
(II) position and the shif t lever is in
the D position.
Use this position f or
your normal driving. The
transmission automatically selects a
suitable gear (1 through 5) f or your
speed and acceleration. You may
notice the transmission shif ting up at
higher engine speeds when the
engine is cold. This helps the engine
warm up f aster.
Af ter you stop in D, 2, 1, N, or R
position with the ignition switch in
the ACCESSORY (I) position f or an
extended period, you may not be
able to move the shift lever from
neutral to reverse or Park. In this
case, press the brake pedal, and turn
the ignition switch to the ON (II)
position, then shif t out of neutral. Use neutral if you
need to restart a stalled engine, or if
it is necessary to stop brief ly with
the engine idling. Shif t to the Park
position if you need to leave your
vehicle for any reason. Press on the
